The deal will create the world's largest brewer by far (Source: Getty)

The megabrew deal is finally on: SABMiller and AB InBev have reached an agreement on a buyout deal that could create the world’s biggest brewing company by far.

Investors flocked to SABMiller, making it the FTSE's biggest riser after news broke this morning that the world’s two biggest beer-makers had agreed in principle a takeover worth £44 a share to SABMiller shareholders, just one day before the 14 October deadline.

SABMiller said in a statement released this morning:

The board of SABMiller has indicated to AB InBev that it would be prepared unanimously to recommend the all-cash offer of GBP 44.00 per SABMiller share

The deal comes after several increasingly sweetened offers from AB InBev that have been rebutted by SABMiller. The suitor offered £43.50 a share just yesterday, at a 48 per cent premium on SABMiller’s share price before the possible offer was made public.

SABMiller shares have soared on the news, rising nine per cent in morning trading to make it the FTSE's leader. AB InBev shares, meanwhile, were largely unchanged.

The British brewer's shares have leapt since confirming in mid-September that rival Anheuser-Busch InBev would be making an offer.

The deal between the two brewers will create a company with a market capitalisation of £162bn.
